IMPROVEMENT l SHUTTER-FASTENINGS.

Specification forming part of Letters Patent No. [94,333, dated August21', 1877; application filed July 16, 1877.

annexed drawings, making a part of this specification, in which likeletters of reference refer to like parts, and in Which- Figure 1represents a vertical section longitudinally through the lock, sash-bar,and blind; Fig. 2, an elevation of window-blind and lock; Fig. 3, asuperficial view of the catch and its case; Fig. 4, perspective view ofshort operating lever; Fig. 5, perspective view of top or cover of case.

, The object of this invention is to lock outside blinds from theinterior side of the sash, or rather to have a lock or blind-catch inwhich all access (with a view to unfastening the blinds) is impossiblefrom outside of the room. I affix the lock or case which contains apivoted spring hook or catch to the underlower surface of the uppersash, at its middle and opposite the junction of the outside blinds, insuch a manner that a hook on one of the blinds enters said lock, and isso secured, and capable of release, by means of a wire or cord passingfrom the end of the catch upward, through a small hole in said box, anda continuation of the same through the sash-bar above it, to a pivotedlever or other device attached to the window-frame above, from which acord may descend within reaching distance of a persons hand, so that aslight downward pull will liberate the blinds. Any similar device may beemployed for the tension of the cord or wire which leads to interior ofthe lock with equal eflect, all as hereinafter more fully described andclaimed.

The usual form in which I construct my device is as follows:

In the drawings, A represents the blinds; B, the lower bar of the uppersash; 'D, the main part of the lock or catch case, which is an oblongtrough or box provided with flanges or ears ff, pierced with holes, bywhich it is screwed to the under side of the lower sashbar B, at themiddle of the latter, so as to receive at its open end the hook G ofsaid blind, its inner end not passing beyond the vertical inner surfaceof said sash, so as to allow the lower sash to pass up or down. E is thecase-cover, of nov importance except to close up the inner end of thecase, and by means of its lugs g g to press upon the trunnions d d ofthe catch, to keep the spring from displacing said catch. It has aperforation, k, for the passage of the managingwire H, and ears 7: t tosupport that end in the recesses t" t in the top of main case D. F isthe pivoted catch, hung near its middle upon its trunnions d d, incorresponding recesses in the sides of the .case D, near the upper partof the latter, to leave room for a nipple and coiled spring, m, beneathits outer arm or hook end. The catch-hook is on the upper side of itsarm, which arm, as well as...

its other arm, is curved downward from the trunnions, in order to makeroom, as before explained, for the spring m. The inner end of the catchhas a wire or cord attached at e, under the opening it in the cover E,in a line with the passage at, up through the sash-bar B. G is the hook,of common form, on the inside of the (overlapping) blind A. H is thecatch cord or wire running upward through the sash-bar B to the innerarm of a short oscillatory lever, I, attached through a slot in itscenter to the under side of the windowframe, by means of a screw orstem.

The operation of this lock is as follows: The hook G of blind A is heldwithin the lock D by the book of the catch F, without danger frommanipulation from outside the room, looking at once both blinds and theupper sash. All chance for burglars to tamper with the catch iseffectively out 01f by the inclosing-box D E, excepting through theperforation 7c in the cover E, and the wire or cord passage it throughthe inner edge of the sash, where the wire or cord H, the lever 1, andcord 0 form the only means of detaching the hooks.

What I claim as my invention is- 1. A closed case, D, attached to theunder surface of the sash-bar B, and entirely closed on its upper sideby a plate or the sash-bar, excepting at a small wire or cord passage,k, beneath the extension-passage n in said bar,

and at the hook entrance 1), at its outer end, In testimony that I claimthe foregoing in combination with a pivoted spring-hook, F, window-blindlook, I have hereunto set my or catch, and wire or cord H, substantiallyas hand this 4th day of July, A. D. 1877.

p and for the purposes described.

2. The combination and arrangement of the ASA J. COLE. hook G attachedto shutter or blind A, the housed catch F, (housed in case D E, attachedWitnesses: to lower edge of sash B,) cord or wire H, le- LUTHER THURLOW,ver 1, and cord 0, substantially as and for the p H. W. WELLS. purposesdescribed.
